Application of Fault Zone Modeling

Article Preview

Abstract:

In outcrops, a fault often appears to be a geologic body with some volume which is called as a fault zone. In the geologic modeling, a fault is often characterized as a surface which cannot characterize the inner structures of the fault zone and the physical differences led by different clast fillings in the fault zone. So, a new method of fault zone modeling was applied in Weizhou oilfield, the proposed method was as follows: First, the two boundaries of a fault zone were characterized as two surfaces, and the distance between the two surfaces was decided by the extent of the fault zone, and the area between the two boundary surfaces was the fault zone. Second, fault zone could be divided into several parts which would characterize its inner structures and properties. When the fault zone is characterized as a geologic body, its inner structures and properties such as its closure can be characterized, which can provide a geologic model that is closer to the actual for the post numerical reservoir simulation.
